## Discrepancy

NR 1 FUEL TRANSFER CIRCUIT BREAKER 'POPPED' IN-FLIGHT, CAUSE UNKNOWN.  THIS CIRCUIT BREAKER CONTROLS THE FUEL SOLENOID FROM THE LEFT WING AS WELL AS THE TIMER THAT CONTROLS THE SOLENOID.  UNREGULATED FUEL OVERFILLED BOTH FEEDER TANKS THEN WAS PIPED, UNDER PRESSURE (FROM THE PRESSURIZATION IN THE WINGS), UP THROUGH THE FEEDER TANK VENT TO THE VERTICAL STABILIZER JUST BELOW THE STAB JACK.  HERE, FUEL WASHED OVERBOARD, SOME OF WHICH DRAINED DOWN INTO THE TAIL CONE AREA WHERE IT PRESENTED A FIRE HAZARD.  SB F10-259 ADDRESSES THIS PROBLEM, BUT IS NOT AN AD.  THE SYSTEM DOES NOT EASILY ALLOW DETECTION BY THE CREW.  SB F10-259 WAS NOT FULLY ACCOMPLISHED.  (X)
